Annual Performance Test Of Fire Pump As Per Nfpa 25 Youtube While a reduction in output is usually a matter of concern, a.8.3.7.1 of nfpa 25 warns that it should be evaluated in light of meeting the pump’s rated characteristics. to pass an annual flow test, fire pump performance at each flow and pressure point must not be less than 95 percent of the nameplate data. The weekly or monthly no flow (churn) test is an important part of ensuring that a fire pump can be continually relied upon in the event of a fire. weekly or monthly no flow tests of fire pumps | nfpa.
The Fire Pump Flow Test Nfpa 25 Annual Fire Pump Tests 2022 Keep sprinkler systems up and running in an emergency with annual fire pump tests in nfpa 25. with costs that start at $20,000 and can pass $1 million when suction tanks are required, fire pumps rank as the most expensive parts of water based sprinkler systems. but their presence is essential at sites that need enhanced water pressure or don.

As shown in figure 1, a pump test flow greater than 2,540 gpm results in unacceptable pressure in the public water supply. most importantly, if the maximum sprinkler system flow demand is less than 2,540 gpm, this reduced acceptance test flow rate is acceptable, and the test complies with nfpa 20 requirements. testing at 150 percent rated flow. Nfpa 25 § 8.3.7.3 and § 8.3.7.4 outline what is considered acceptable when it comes to the fire pump performance test. it states that if a pump yields results less than 95% of the pump’s rated pressure and flow, than an investigation must be conducted as to why the pump is yielding a degraded performance.
